SNAP SEAL. APPLICATION FILED SEPT-25,1915.

ATTORNEY Ton ZZZ mam at may concern Be it known that I, GEORGEGQRDON, a citizen of the United. States, residing at Saginaw, in the county of Saginaw and State of Michigan, have invented certain new and useful Improvements in Snap- Seals; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to snap seals and pertains more particularly to that type of snap seals in which. a flexible strap is'employed having a hooked end, and carrying at its opposite end a seal body, in which the hook is received and automatically locked.

My improvement relates more particularly to the construction of the seal body and the hook-locking means, the said construction producing a seal that is simple, yet

positive in operation, and that is capable of being manufactured at a very small cost.

My invention consists in the devices and combinations set forth and claimed and the equivalents thereof.

In the drawings, Figure 1 represents a one-piece blank, from which the seal is formed. Fig. 2, is a perspective view of the blank partly formed, showing the method of folding it. Fig. 3 shows the seal assembled. Fig. is an enlarged section taken on line 33 of Fig. 3, the relative proportions of the parts being distorted for the purpose of better illustration. Fig. 5 is a plan view of a blanked sheet of metal, from which a number of the seals are formed. Fig. 6 is aperspective view of the sheet shown in Fig. 5, the ends of the sheet being folded, prior to being sheared into a plurality of finished seals.

In the drawings, 1 is a flexible strap of thin tin, or other suitable material, one end of which is bent to form a hook 2. At the other extremity of the strap is a seal body 8, which consists in a depressed pocket lformed near one end of the strip, as shown in Fig. l.

The metal of the overlapping end '6 is preferably formedwith a transverse slit 7, and pressed up, as at 8, at one edge of the slit 7, to convert the slit into aslightly raised opening, to more readily receive the hook 2. The free end of the overlapping "Boner. sea ort, gonsaiifanf, iii ciireAiiI" ssuer-snarl.-

part 6 ispreferably fixed to the flexible strap 1, as at 9, by spot-welding or otherrose. In u s,.."E -he strap 1jis bent, as. shown in Fig. 8, and the hook is inserted inthe raised slit of the seal-body 3 until the freeend of the hook. has passed into the body of the seal. The hook is then drawn-back until its end. brings up against the end of the ole pressed pocket, as shown in Fig. i. The fold of the hook then lies beyond. the slit and the hook can not be drawn out without breaking it, thereby showing that the seal has been tampered with. I

The seal may be manufactured in any suitable or usual manner, but to illustrate an advantage of manufacture which arises from the design and arrangement of the seal, I have shown in Figs. 5 and 6, a sheet of metal which is adapted at one operation to have formed in it a large number of the pockets l, the slits 7, and the'pressed-up edges 8, and at a second operation the sheet may have its ends folded up to form the hooks and the overlapping members 6, thus simultaneously forming in one sheet a large number of seals. A spot-weld is then formed in front of each slit along the sheet, as at 9, and the sheet is then put through a shearing die that severs it progressively into a large number of completed seals.

While I do not desire to confine myself to this specified method of manufacture, I have shown and described that method as being an. economical manufacturing procedure that is made possible by the construction of, the seal which is herein de scribed.

Having thus described my inventiomwhat I claim and desire to secure by Letters Patent is:

1. A snap seal comprising a flexible strap formed at one end with a hook and shaped at its opposite end to form a hook-receiving body, said body comprising a depressed pocket in said strap near one end thereof, the end of said strap overlapping and iorming a cover for the depressed pocket, the overlapping part welded to said strap at a point near the forward end of the pocket,-

formed at one end with a-hook and having at its opposite end a hook-receiving body,

said 'body'icomprising a depressed pocket formed' in-"said strap near one endthereof, the end of said strap overlapping the depressed pocket, the overlapping part welded to. saidstrap at a point in advance of the end of the pocket,- said overlapping part forI-ri'ed with atransverse hook-receiving slit above the pocket, the metal at one edge of the slit raised to form an opening adapted to receive said hook, the opening so positioned relatively to the end of the depressed pocketjas fto engage the'tang of the hook against at-he end of the pocket to prevent Withdrawal of the hook through the slit.

In testimony whereof, I aifix my signature in presence of two Witnesses.
